Can you tell us more about what issues he has with you?
What has he said that he dislikes?
What are some of the promised changes that you have already not followed through on?
What problems do you see in yourself right now?
We need some more information in general to see what it is that youre working with here. Try to fill in the blanks here with a little more detailed history and try to be as thorough as possible.
The main thing that I see here so far is that you are wanting to talk about your changes. Dont talk about them. Do them. Let him see you changing and dont bring it up at all. Dont ask if he has noticed. Dont try to point it out. Let him see them on his own. And be consistent in whatever they are. You need to make them a permanent thing and not something that is to win him back. He has no reason to trust that you will make the changes and for them to stick based on what youve already told us.
Thats really all the advice I can offer based on the information that you have given. Keep posting here often and we can dig deeper into some of these issues.
